I have received several calls a day for several days.  The one call I answered said it was some type of survey, I told them my opinion was none of theirs, and not to call back.  They did, I used the foulest language I could think of, and was advised not to use that type of language, in which I answered "I asked you not to call here, it's my phone,  you called, and you will hear anything I want to say.   More calls......  I finally got smart and blocked the number.  This group is none to smart.  so far 7 calls today on block.
